}

public class Test {
    public static void main(String[] args) {
        Season a=Season.SPRING;
        switch (a) {
        case SPRING:
            System.out.println("春天");
            break;
        case SUMMER:
            System.out.println("夏天");
            break;
        case AUTUMN:
            System.out.println("秋天");
            break;
        case WINTER:
            System.out.println("冬天");
            break;
        }
